教师,学生和地址表的最佳方法数据库结构是什么? [关闭]

I have the following tables in my database

  • students
  • teachers
  • address

I Want to store basic information about students and teacher in its own table, but the address and contact information in address table. If I store the student_id or teacher_id in address table, the student might have same id as any teacher. If I try to query any teacher address by teacher_id. It will query the student who has the same id as well.

So what the best way to figure out this problem? should I create any other table as well or ....

Please suggest me an easiest and best approach.

thanks.
